Fix: GPG tmp dir removal race condition

Ignore any errors when removing the tmp directory, as we may run into a
race condition:
The `gpg-agent` agent process may clean up some files as well while
`FileUtils.remove_entry` is iterating the directory and removing all its
contained files and directories recursively, which could raise an error.
